As wireless technologies like 5G, 6G, IoT, and Cognitive Radio grow rapidly, spectrum access systems (SAS) face major threats: Denial-of-Service (DoS) attacks, location tracking, and the rising risk of quantum computers breaking today’s encryption. Existing solutions fall short—they don’t scale well, don’t protect user privacy, and aren’t built for the post-quantum era. These issues are critical because they threaten the availability and security of spectrum services, which are essential for everything from smart cities to connected healthcare.
Our technology introduces a Post-Quantum Secure and Privacy-Preserving Counter-DoS system that protects spectrum management from both current and future cyber threats. It uses Private Spectrum Bastions (PSBs) to distribute quantum-safe puzzles and combines this with Post-Quantum Tor (PQ-Tor) and Private Information Retrieval (PIR) to keep users anonymous and compliant with FCC rules. We’ve tested the system using real cryptographic tools—like KYBER, Dilithium, and G6K—and simulated databases, showing fast puzzle solving, low-latency performance, and strong privacy. What sets this apart is its future-proof design, regulatory readiness, and ability to scale across different network environments.
